Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - ttyn_gsm新增 gsm_receive_buf() 中 gsm->receive 的功能健全檢查。嘗試存取 gsmld_receive_buf() 中的 gsm->receive() 函式時可能會發生 null 指標解除參照。目前程式碼會假設 gsm->recieve 只會在 MUX 啟動後呼叫。由於無需初始化 MUX即可存取 gsmld_receive_buf() 函式因此將不會設定 gsm->receive() 函式且會發生 NULL 指標解除參照。避免在函式未透過新增功能健全檢查初始化的情況下呼叫 gsm->receive()以修正此問題。呼叫追踪 <TASK> gsmld_receive_buf+0x1c2/0x2f0 drivers/tty/n_gsm.c:2861 tiocsti drivers/tty/tty_io.c:2293 [內嵌] tty_ioctl+0xa75/0x15d0 drivers/tty/tty_io.c:2692 vfs_ioctl fs/ioctl .c:51 [內嵌] __do_sys_ioctl fs/ioctl.c:870 [內嵌]

  - 已解決 Linux 核心中的下列弱點：net: qrtr: start MHI channel after endpoit creation MHI channel may generates event/interrupt right after enabling. It may leads to 2 race conditions issues. 1) Such event may be dropped by qcom_mhi_qrtr_dl_callback() at check: if (!qdev || mhi_res->transaction_status) return; Because dev_set_drvdata(&mhi_dev->dev, qdev) may be not performed at this moment. In this situation qrtr-ns will be unable to enumerate services in device.
    --------------------------------------------------------------- 2) Such event may come at the moment after dev_set_drvdata() and before qrtr_endpoint_register(). In this case kernel will panic with accessing wrong pointer at qcom_mhi_qrtr_dl_callback(): rc = qrtr_endpoint_post(&qdev->ep, mhi_res->buf_addr, mhi_res->bytes_xferd); Because endpoint is not created yet.
    -------------------------------------------------------------- So move mhi_prepare_for_transfer_autoqueue after endpoint creation to fix it. (CVE-2022-50044)

  - 已解決 Linux 核心中的下列弱點：rcutorture: Fix ksoftirqd boosting timing and iteration The RCU priority boosting can fail in two situations: 1) If (nr_cpus= > maxcpus=), which means if the total number of CPUs is higher than those brought online at boot, then torture_onoff() may later bring up CPUs that weren't online on boot. Now since rcutorture initialization only boosts the ksoftirqds of the CPUs that have been set online on boot, the CPUs later set online by torture_onoff won't benefit from the boost, making RCU priority boosting fail. 2) The ksoftirqd kthreads are boosted after the creation of rcu_torture_boost() kthreads, which opens a window large enough for these rcu_torture_boost() kthreads to wait (despite running at FIFO priority) for ksoftirqds that are still running at SCHED_NORMAL priority.

CentOS Linux 8.4 主機已安裝的套件會受到 TuxCare CENTOS8.4：CLSA-2025：1753297988 公告中提及的多個弱點影響。

  - 已解決 Linux 核心中的下列弱點：mptcp: fix race on unaccepted mptcp sockets When the listener socket owning the relevant request is closed, it frees the unaccepted subflows and that causes later deletion of the paired MPTCP sockets. The mptcp socket's worker can run in the time interval between such delete operations. When that happens, any access to msk->first will cause an UaF access, as the subflow cleanup did not cleared such field in the mptcp socket. Address the issue explicitly traversing the listener socket accept queue at close time and performing the needed cleanup on the pending msk. Note that the locking is a bit tricky, as we need to acquire the msk socket lock, while still owning the subflow socket one. (CVE-2022-49669)

  - 已解決 Linux 核心中的下列弱點：tty: n_gsm: add sanity check for gsm->receive in gsm_receive_buf() A null pointer dereference can happen when attempting to access the gsm->receive() function in gsmld_receive_buf(). Currently, the code assumes that gsm->recieve is only called after MUX activation. Since the gsmld_receive_buf() function can be accessed without the need to initialize the MUX, the gsm->receive() function will not be set and a NULL pointer dereference will occur.
    Fix this by avoiding the call to gsm->receive() in case the function is not initialized by adding a sanity check.
